BOAT AND MEANS FOR PHOF'ELLING SAME.n

SPECIFICATION forming part of Letters Patent N0. 780,071, dated January 1'7, 1905.

Application filed July 29, 1904:. Serial No. 218,696.

To all whom it may concern.-

Be it known that I, HERMANN STAsNY, a subject of the German Emperor, residing and having my post-oilice address at 43 Mittelweg, Frankfort-on-the-Main, Germany, have invented certain new and useful Improvements in Boats and Means for Propelling Same, of which the following is a specification.

The present invention relates to improvements in boats and means for propelling same, said means comprising a slide provided with movable paddles and adapted to be reciproeated longitudinally of the boat and mechanism for operating said slide, the latter being connected to an endless chain driven by a second endless chain adapted to be moved to and fro by means of a handle.

The invention is illustrated in the annexed drawingsfigure 1 being a longitudinal section of the boat on line AB of Fig. 2, which latter figure is a plan View.

The boat consists of two half parts or sections of boat-body a a, in which the oarsman is to sit, and these each have a curved side and a straight side, and the straight sides of the two sections are arranged opposite each other. The sections are connected together by a frame I), having the form of the two sections cm of the body and a connection between them at the ends and comprising a flat iron frame or the like, and this serves to hold the two sections togetheigleaving a space between the two sections for the reception of the operating mechanism. The sliding seat or seats for the operator or operators is or are fixed to said frame in one or each half of the boat in any suitable and known manner.

At the stern of the boat two horizontal shafts (Z and d are mounted in bearings c 0, fixed to the frame 7), one of said shafts, (Z, carrying three chain-wheels a, of equal diameter, and the othershaft, (Z, carrying a chain-wheel of larger diameter and two chain-wheels g of smaller diameter than the aforesaid wheels 6. At the bow part of the boat two other horizontal shafts v1 and vi are also mounted in bearings 71 laiixed to the frame 7), one of these shafts, marrying a Cl]ttll1-\Vl1GGl/72tlld the other shaft, 1:, carrying a chain-wheel l, the diame ter of which is greater than that of the wheel /r:.

The central wheel of the three chain-wheels c at the stem is connected by an endless chain in to the smaller chain-wheel Z: in the bow, and on this chain is arranged a transverse handle or, adapted to be reciprocated by the operators in the half parts of the boat. On this re ciprocation of thehandle the chain m is given a corresponding movement, so that the three stern-wheels and the how-wheel 7r: are rotated. The rotation of the shaft (Z, carrying said wheels 0, is transi'nitted by two outer wheels, by means of chains 0 and the small stern-wheels g, to the outer shaft d at an increased speed in the ratio chosen. The large chain-wheel on said shaft (1 is thus revolved, and said wheel f is connected by a second endless chain 33 to the larger bow chain-wheel Z. By the arrangement of the various chainwheels and their different relative connections the reciprocating movement given to the chain at is transmitted to the chain 1) in the ratio determined by the diameters of the chain-wheels.

To the inner wall or surface of each half a of the boat is lixed a rail on which a slide or trolley r, conn eeted to the champ, is adapted to run, and on said slide r are paddles s, pivoted in the known manner, so that on the movement of the slides in one direction they assume a vertical position, thus causing the boat to be propelled, and on movement in the opposite direction they assume a horizontal or inclined position and have no action on the water. The operation of the slide,a-nd consequently the propulsion of the boat, is effected in a simple manner by the reciprocating movement of the handle.

I claim as my inventionl. The combination with a boat of a car riage provided with movable paddles and adapted to be reciprocated longitudinally of the boat by an endless chain connected to said carriage, chain-wheels mounted on shafts i d and carrying said chain. a second endless chain,chain-wheels mounted on shafts (Z i and carrying said second chain, a handle connected to the latter and transmission-gear between the aforesaid shafts (Z and (Z substantially as described.

2. The combination with a boat comprising 10 connected to the latter, and variable-speedtransmission gear between the aforesaid shafts (Z and (Z substantially as described,

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

HERMANN STASN Y.
